I'm on OS_x El Capitan on a 2009 Mac Pro at home and Sierra on my work current gen Mac pro.

I run the latest Arduino for my 3d printer to load the firmware etc.How do I install the RA and the Arduino as two "seperate" things? On my PC they instaled as two seperate things but on the Mac I was getting weird errors and on Sierra I had to install an old Java version. I tried to download the latest RA IDe version from here but if have Arduiino and RA installed the RA says it's corrupt and the Arduino stops working.

It's most likely that I'm doing something wrong. Can anyone shed some light for me?

Thanks

Believe it or not.... I can ask even stupider questions than this one.
